------------------------------------
Summary: Add class PairList
Key: CALCITE-5706
URL: https://issues.apache.org/jira/browse/CALCITE-5706
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Add a {{class PairList}} which an implementation of {{List<Map.Entry<K, V>}}
backed by a single list. It can be used to build two lists in parallel (e.g. a
list of field types and field names that will be converted to a struct type);
it can also be used to build maps.
It has a {{forEach(BiConsumer<K, V>)}} method to allow the list to be
deconstructed without creating intermediate entries.
Potentially also {{toImmutableMap}} and {{toHashMap}} methods.
